I'm going to be leaving for an eleven day vacation in around two weeks, and I cannot bring my birds with me. I am going to be leaving them at my friend's house, and he's completely trustworthy and listens to everything I say to do with my birds. The ride from my house to his is not very long. It's around ten minutes, but, as I live out in the country, some roads get pretty bumpy. Is there anything I should do to make sure my birds stay as safe as possible on this little drive? They'll be in their cage and I was thinking I could place a blanket over the cage so that they won't get too startled by things around them. They are not tame, so I cannot take them out and hold them on my fingers as we go. As far as I know, I'm going to be sitting in the back of the car with the cage, making sure it stays as steady as possible and making sure the blanket stays on them. Will this be alright for a ten minute drive?
